ABSTRACT:
A system is provided for receiving audio signals from a plurality of microphones and transferring the audio signals via a common composite signal channel to a receiving unit, such as a mixing console. The system has at least two satellite units, each having a microphone signal input, a composite signal channel input and summing means for summing a microphone signal and a composite signal. The system further has a master unit with a composite signal channel input, and signal converting means for converting said composite signal into a master signal, which is provided to the receiving unit via a master signal output. In the system, each satellite unit is connected to the common composite signal channel, such that the microphone signal received at the respective satellite unit, is added to the composite signal, which is fed to the master unit.A satellite unit and a master unit for use in the system are also disclosed, as well as a method for receiving audio signals from a plurality of microphones and transferring the audio signals to a receiving unit via a common signal channel, such as a mixing console.
